This application is a continuation-in-part of co-pending PCT Application, Serial No. PCT/US22/15564, entitled SYSTEM AND METHOD FOR BANDWIDTH REDUCTION AND COMMUNICATION OF VISUAL EVENTS, filed Feb. 8, 2022, which is based upon U.S. patent application Ser. No. 17/175,364, entitled SYSTEM AND METHOD FOR BANDWIDTH REDUCTION AND COMMUNICATION OF VISUAL EVENTS, filed Feb. 12, 2021, now U.S. Pat. No. 11,132,552, issued Sep. 28, 2021.

FIELD OF THE INVENTION

This application relates to systems and methods for communicating visual data and related events over a communication link, and user interfaces for viewing and manipulating such data and events.

BACKGROUND OF THE INVENTION

International shipping is a critical part of the world economy. Ocean-going, merchant freight vessels are employed to carry virtually all goods and materials between ports and nations. The current approach to goods shipments employs intermodal cargo containers, which are loaded and unloaded from the deck of ships, and are carried in a stacked configuration. Freight is also shipped in bulk carriers (e.g. grain) or liquid tankers (e.g. oil). The operation of merchant vessels can be hazardous and safety concerns are always present. Likewise, passenger vessels, with the precious human cargo are equally, if not more, concerned with safety of operations and adherences to rules and regulations by crew and passengers. Knowledge of the current status of the vessel, crew and cargo can be highly useful in ensuring safe and efficient operation.

In many areas of commercial and/or government activity, visual monitoring (manual and automated surveillance), and other status sensors is employed to ensure safe and rule-conforming operation. These approaches, however, entail the generation and transmission of large volumes of data to a local or remote location, where such data is stored and/or analyzed by management personnel. However, unlike most land-based (i.e. wired, fiber or high-bandwidth wireless) communication links, it is often much more challenging to transmit useful data (e.g. visual information) from ship-to-shore. It can be assumed that ten (10) channels of raw video data are the minimum number needed to provide shipboard visibility and a 5 Mb/s of uplink speed per HD video channel or 50 Mb/s in aggregate is required. Conversely a typical satellite link to/from a ship is 1/200 or 1/400 of that size, and transmits only 256 Kb/s or 128 Kb/s.

It is desirable to provide a system and method that enables continuous visibility into the shipboard activities, shipboard behavior, and shipboard status of an at-sea commercial merchant vessel (cargo, fishing, industrial, and passenger). It is further desirable that that the transmitted visual data and associated status be accessible via an interface that aids users in manipulating, organizing and acting upon such information.

Digital communication between ships, and with shore-based resources, is highly desirable to allow interested parties and stakeholders to have a mechanism to share commentary and information related to various shipboard operations. While there are a plethora of commercially available collaboration tools (typically Internet-based), there are no tools adapted particular to a maritime environment.

SUMMARY OF THE INVENTION

This invention overcomes the disadvantages of the prior art by providing a system and method that can optionally employ reduction in bandwidth and the amount of data stored bandwidth, along with queuing of data so that the significant and/or relevant shipboard visual information is detected and communicated continuously from the ship (or other remote vehicle/location) to shore without (free of) the loss of useful/high-priority information and within the available bandwidth of that typical, available satellite link. The system and method supports remote configuration and management from shore to the ship over the same communications channel but in the reverse direction. The system and method further facilitates the logical summarization of continuous visibility into shipboard activities, shipboard behavior, and shipboard status so that a land/shore-based manager/reviewer/auditor can review, comprehend and synthesize such information, at a glance, using a land-based computer graphical user interface (GUI), which can be defined by a dashboard, related to events that have recently transpired on the sailing commercial merchant vessel without the need to review hours/days/weeks of (e.g.) 10+ channels of video. Notably, the system and method effectively provides that visibility to the land-based computer dashboard.

In an illustrative embodiment, a system and method for fleet management, including handling visual events in association with an activity, is provided. One or more visual event detector(s) is/are provided, having at least one camera that acquires images of the activity, and a processor that receives the images. A visual event detection process operating on one or more computer systems, operates to process the images. A queuing process identifies visual events from the visual event detector and stores the visual events. A communications process transmits the stored visual events in a queued format to a remote location. A display that is accessed by users to view visual events, and a collaboration process displays information related to collaboration between permitted users based upon a context of each of the visual events—which can comprise fleet management activities related to at least one of bridge operations, cargo operations, maintenance operations, safety operations, and vetting and security with respect to a vessel. Illustratively, the collaboration process is accessible via a browser button on the display, and when activated, opens a pane that allows the users to perform the collaboration. The communications process can enable a reduced-bandwidth communications channel adapted to transmit the stored visual events in a reduced bandwidth. Additionally, the visual events can provide data primitives that are derived into user information. These data primitives can include at least one of statistics, pattern matches, metrics and time. The stored visual events can be communicated across the communications channel based upon user-set priorities, wherein higher priority events are communicated first in a queue from the stored visual events. Illustratively, a user interface can display information of the at least one of the bridge operations, cargo operations, maintenance operations, safety operations, and vetting and security at a base location in one or more predetermined presentation formats. The user interface can further include inputs that enable the user-set priorities and/or inputs that enable adding or setting configuration parameters for the event detectors. The user information can include at least one of fleet reports on a plurality of vessels associated with the user interface, vessel reports, occurrence of discrete events and occurrence of complex events comprising a plurality of discrete events. The information can be displayed in a dashboard format comprising one or more visual windows, alerts and numerical data. Illustratively, the collaboration process can include functions that enable one or more of (a) simultaneous document editing, (b) whiteboarding, (c) sticky notes, (d) text chat, (e) notification, (f) video conferencing, (g) audio conferencing, and (h) contextual commenting. Additionally, the collaboration can, respectively, permit access by each of the users based upon context of the visual event and permissions assigned to each of the users.

DETAILED DESCRIPTION

I. System Overview

FIGS. 1 and 1A show an arrangement 100 for tracking and reporting upon visual, and other, events generated by visual sensors aboard ship that create video data streams, visual detection of events aboard ship based on those video data streams, aggregation of those visual detections aboard ship, prioritization and queuing of the aggregated detections into events, bandwidth reduction of the video data streams in combination with the aggregated events, sending the events over the reduced bandwidth communications channel to shore, reporting the events to a user-interface on shore, and further aggregation of the events from multiple ships and multiple time periods into a fleet-wide aggregation that can present information over time. The system and method herein further provides the ability to configure and setup the system described above to select or not select events for presentation in order to reduce confusion for the person viewing the dashboard as well as to set the priority for communicating particular events or classes of events over the reduced bandwidth communications channel so that the most important events are communicated at the expense of less important events.

FIG. 1, the arrangement 100 particularly depicts a shipboard location 110 includes a camera (visual sensor) array 112 comprising a plurality of discrete cameras 118 (and/or other appropriate environmental/event-driven sensors) that are connected to wired and/or wireless communication links (e.g. that are part of a TCP/IP LAN or other protocol-driven data transmission network 116) via one or more switches, routers, etc. 114. Image (and other) data from the (camera) sensors 118 is transmitted via the network 116. Note that cameras can provide analog or other format image data to a remote receiver that generates digitized data packets for use of the network 116. The cameras 118 can comprise conventional machine vision cameras or sensors operating to collect raw video or digital image data, which can be based upon two-dimensional (2D) and/or three-dimensional (3D) imaging. Furthermore, the image information can be grayscale (monochrome), color, and/or near-visible (e.g. infrared (IR)). Likewise, other forms of event-based cameras can be employed.

Note that data used herein can include both direct feeds from appropriate sensors and also data feeds from other data sources that can aggregate various information, telemetry, etc. For example, location and/or directional information can be obtained from navigation systems (GPS etc.) or other systems (e.g. via APIs) through associated data processing devices (e.g. computers) that are networked with a server 130 for the system. Similarly, crew members can input information via an appropriate user interface. The interface can request specific inputs—for example logging into or out of a shift, providing health information, etc.—or the interface can search for information that is otherwise input by crew during their normal operations—for example, determining when a crew member is entering data in the normal course of shipboard operations to ensure proper procedures are being attended to in a timely manner.

The shipboard location 110 can further include a local image/other data recorder 120. The recorder can be a standalone unit, or part of a broader computer server arrangement 130 with appropriate processor(s), data storage and network interfaces. The server 130 can perform generalized shipboard, or dedicated, to operations of the system and method herein with appropriate software. The server 130 communicates with a work station or other computing device 132 that can include an appropriate display (e.g. a touchscreen) 134 and other components that provide a graphical user interface (GUI). The GUI provides a user on board the vessel with a local dashboard for viewing and controlling manipulation of event data generated by the sensors 118 as described further below. Note that display and manipulation of data can include, but is not limited to enrichment of the displayed data (e.g. images, video, etc.) with labels, comments, flags, highlights, and the like.

The information handled and/or displayed by the interface can include a workflow provided between one or more users or vessels. Such a workflow would be a business process where information is transferred from user to user (at shore or at sea interacting with the application over the GUI) for action according to the business procedures/rules/policies. This workflow automation is commonly referred to as “robotic process automation.”

The processes 150 that run the dashboard and other data-handling operations in the system and method can be performed in whole or in part with the on-board server 130, and/or using a remote computing (server) platform 140 that is part of a land-based, or other generally fixed, location with sufficient computing/bandwidth resources (a base location 142). The processes can generally include 150 a computation process 152 that handles sensor data to meaningful events. This can include machine vision algorithms and similar procedures. A data-handling process 154 can be used to derive events and associated status based upon the events—for example movements of the crew and equipment, cargo handling, etc. An information process 156 can be used to drive dashboards for one or more vessels and provide both status and manipulation of data for a user on the ship and at the base location.

Data is communicated between the ship (or other remote location) 110 and the base 142 occurs over one or more reduced-bandwidth wireless channels, which can be facilitated by a satellite uplink/downlink 160, or another transmission modality—for example, long-wavelength, over-air transmission. Moreover, other forms of wireless communication can be employed such as mesh networks and/or underwater communication (for example long-range, sound-based communication and/or VLF). Note that when the ship is located near a land-based high-bandwidth channel or physically connected by-wire while at port, the system and method herein can be adapted to utilize that high-bandwidth channel to send all previously unsent low-priority events, alerts, and/or image-based information.

The (shore) base server environment 140 communicates via an appropriate, secure and/or encrypted link (e.g. a LAN or WAN (Internet)) 162 with a user workstation 170 that can comprise a computing device with an appropriate GUI arrangement, which defines a user dashboard 172 allowing for monitoring and manipulation of one or more vessels in a fleet over which the user is responsible and manages.

Referring further to FIG. 1A, the data handled by the system is shown in further detail. The data acquired aboard the vessel environment 110, and provided to the server 130 can include a plurality of possible, detected visual (and other sensor-based) events. These events can be generated by action of software and/or hardware based detectors that analyze visual images and/or time-sequences of images acquired by the cameras. With further reference to FIG. 1B, visual detection is facilitated by a plurality of 2D and/or 3D camera assemblies depicted as cameras 180 and 182 using ambient or secondary sources of illumination 183 (visible and/or IR). The camera assemblies image scenes 184 located on board (e.g.) a ship. The scenes can relate to, among other subjects, maritime events, personnel safety and/or cargo. The images are directed as image data to the event detection server or processor 186 that also receives inputs from a plan or program 187 that characterizes events and event detection and a clock 188 that establishes a timeline and timestamp for received images. The event detection server or processor 186 can also receive inputs from a GPS receiver 189 to stamp the position of the ship at the time of the event and can also receive input from an architectural plan 190 of the vessel (that maps onboard locations on various decks) to stamp the position of the sensor within the vessel that sent the input. The event server/processor 186 can comprise one or more types and/or architectures of processor(s), including, but not limited to, a central processing unit (CPU—for example one or more processing cores and associated computation units), a graphical processing unit (GPU—operating on a SIMD or similar arrangement), tensor processing unit (TPU) and/or field programmable gate array (FPGA—having a generalized or customized architecture).

Referring again to FIG. 1A, the base location dashboard 172 is established on a per-ship and/or per fleet basis and communicates with the shipboard server 130 over the communications link 160 in a manner that is typically reduced in bandwidth, and possibly intermittent in performing data transfer operations. The link 160 transmits events and status updates 162 from the shipboard server 130 to the dashboard 172 and event priorities, camera settings and vision system parameters 164 from the dashboard 172 to the shipboard server. More particularly, the dashboard displays and allows manipulation of events reports and logs 173, alarm reports and logs 174, priorities for events, etc. 175, camera setup 176 and vision system task selection and setup relevant to event detection, etc. 177. The shipboard server 130 includes various functional modules, including visual event bandwidth reduction 132 that facilitates transmission over the link 160; alarm and status polling and queuing 133 that determines when alarms or various status items have occurred and transmits them in the appropriate priority order; priority setting 134 that selects the priorities for reporting and transmission; and a data storage that maintains image and other associated data from a predetermined time period 135.

Note that, in various embodiments, the bandwidth of the communications link between vessel and base can be limited by external systems such as QoS-quality of service-settings on routers/link OR by the internal system (edge server 130)—for example to limit usage to (e.g.) 15% of total available communication bandwidth. This limitation in bandwidth can be based on a variety of factors, including, but not limited to, the time of day and/or a communications satellite usage cost schedule. An appropriate instruction set can be programmed into the server using conventional or custom control processes. The specific settings for such bandwidth control can also be directed by the user via the GUI.

II. Visual Detectors

As shown in FIG. 1B, various imaged events are determined from acquired image data using appropriate processes/algorithms 188 performed by the processor(s) 186. These can include classical algorithms, which are part of a conventional vision system, such as those available from (e.g.) Keyence, Cognex Corporation, MVTec, or HIKVision. Alternatively, the classical vision system could be based on open source such as OpenCV. Such classical vision systems can include a variety of vision system tools, including, but not limited to, edge finders, blob analyzers, pattern recognition tools, etc. The processor(s) 186 can also employ machine learning algorithms or deep learning algorithms, which can be custom built or commercially available from a variety of sources, and employ appropriate deep-learning frameworks such as caffe, tensorflow, torch, keras and/or OpenCV. The network could be a mask R-CNN or Yolov3 detector. See also URL address https://engineer.dena.com/posts/2019.05/survey-of-cutting-edge-computer-vision-papers-human-recognition/ on the WorldWideWeb.

As shown in FIG. 1A, the visual detectors relate to maritime events 191, ship personnel safety behavior and events 192, maintenance operation and events 193, ship cargo condition and events related thereto 194, and/or non-visual alarms, such as smoke, fire, and/or toxic gas detection via appropriate sensors. By way of non-limiting example, some particular detected events and associated detectors relate to the following:

(a) A person is present at their station at the expected time and reports the station, start time, end time, and elapsed time;

(b) A person has entered a location at the expected time and reports the location, start time, end time, and elapsed time;

(c) A person moved through a location at the expected time and reports the location, start time, end time, and elapsed time;

(d) A person is performing an expected activity at the expected location at the expected time and reports the location, start time, end time, and elapsed time—the activity can include (e.g.) watching, monitoring, installing, hose-connecting or disconnecting, crane operating, tying with ropes;

(e) a person is running, slipping, tripping, falling, lying down, using or not using handrails at a location at the expected time and reports the location, start time, end time, and elapsed time;

(f) A person is wearing or not wearing protective equipment when performing an expected activity at the expected location at the expected time and reports the location, start time, end time, and elapsed time—protective equipment can include (e.g.) a hard-hat, left or right glove, left or right shoe/boot, ear protection, safety goggles, life-jacket, gas mask, welding mask, or other protection;

(g) A door is open or closed at a location at the expected time and reports the location, start time, end time, and elapsed time;

(h) An object is present at a location at the expected time and reports the location, start time, end time and elapsed time—the object can include (e.g.) a gangway, hose, tool, rope, crane, boiler, pump, connector, solid, liquid, small boat and/or other unknown item;

(i) That normal operating activities are being performed using at least one of engines, cylinders, hose, tool, rope, crane, boiler, and/or pump; and

(j) That required maintenance activities are being performed on engines, cylinders, boilers, cranes, steering mechanisms, HVAC, electrical, pipes/plumbing, and/or other systems.

Note that the above-recited listing of examples (a-j) are only some of a wide range of possible interactions that can for the basis of detectors according to illustrative embodiments herein. Those of skill should understand that other detectable events involving person-to-person, person-to-equipment or equipment-to-equipment interaction are expressly contemplated.

In operation, an expected event visual detector takes as input the detection result of one or more vision systems aboard the vessel. The result could be a detection, no detection, or an anomaly at the time of the expected event according to the plan. Multiple events or multiple detections can be combined into a higher-level single events. For example, maintenance procedures, cargo activities, or inspection rounds may result from combining multiple events or multiple detections. Note that each visual event is associated with a particular (or several) vision system camera(s) 118, 180, 182 at a particular time and the particular image or video sequence at a known location within the vessel. The associated video can be optionally sent or not sent with each event or alarm. When the video is sent with the event or alarm, it may be useful for later validation of the event or alarm. Notably, the discrete images and/or short-time video frame sequences actually represent a small fraction of the video stream, and consequently represent a substantial reduction in the bandwidth required for transmission in comparison to the entire video sequence over the reduced-bandwidth link. Moreover, in addition to compacting the video by reducing it to a few images or short-time sequence, the system can reduce the images in size either by cropping the images down to significant or meaningful image locations required by the detector or by reducing the resolution say from the equivalent of high-definition (HD) resolution to standard-definition (SD) resolution, or below standard resolution.

In addition to reducing bandwidth by identifying events via the vision system and cropping such images where appropriate, the number of image frames can be reduced, in a sequence thereof, by increasing the interval of time between frames. Moreover, bandwidth can be even further reduced using the procedures above, and then subjecting (all on the shipboard server side) the event-centric, cropped, spaced-apart, using commercially available or customized lossy or lossless image compression techniques. Such techniques can include, but are not limited to discrete cosine transform (DCT), run-length encoding (RLE), predictive coding, and/or Lempel-Ziv-Welch (LZW).

The images or video sequences NOT associated with visual events may be stored for some period of time on board the vessel.

The shipboard server establishes a priority of transmission for the processed visual events that is based upon settings provided from a user, typically operating the on-shore (base) dashboard. The shipboard server buffers these events in a queue in storage that can be ordered based upon the priority. Priority can be set based on a variety of factors—for example personnel safety and/or ship safety can have first priority and maintenance can have last priority, generally mapping to the urgency of such matters. By way of example, all events in the queue with highest priority are sent first. They are followed by events with lower priority. If a new event arrives shipboard with higher priority, then that new higher priority event will be sent ahead of lower priority events. It is contemplated that the lowest priority events can be dropped if higher priority events take all available bandwidth. The shipboard server receives acknowledgements from the base server on shore and confirms that events have been received and acknowledged on shore before marking the shipboard events as having been sent. Multiple events may be transmitted prior to receipt (or lack of receipt) of acknowledgement. Lack of acknowledgement potentially stalls the queue or requires retransmission of an event prior to transmitting all next events in the priority queue on the server. The shore-based server interface can configure or select the visual event detectors over the communications link. In addition to visual events, the system can transmit non-visual events like a fire alarm signal or smoke alarm signal.

III. Detection Flow

As shown in FIG. 2, an operating procedure 200 for generalized detection flow used in performing the system is shown. The operation can be characterized in three phases or segments, computation 210, generation of data primitives 220 and information creation 230 and presentation 240 to users via the shore-based dashboard. Alternatively, some or all of the functions herein can be implemented by users via a ship-based dashboard, which affects programming on at least one of the local server or the base server. The shipboard dashboard can also act as a passive terminal that transmits instructions back to the base interface over the communications link so that such instructions can be acted upon through the base. The computation phase 210 comprises measurement 212 using sensors and performing visual detection 213. These generate a set of metrics 222 that are displayed to the user as discrete events 232. The computation phase 210 uses event sequencing (priority) 214, filtering (via cropping, compression, etc.), qualification of events 216 based upon rules 217 to provide pattern matches 224 according to a time series of events 226. This data is presented as complex events 234. These complex events 234 can comprise a scenario, such as a maintenance task successfully performed, or the occurrence of a safety breach. The computation phase 210 can aggregate visual and other events 218 and derive statistics 228—for example the number of safety breaches over a time interval, etc. These statistics 228 can be presented to the shore-based user as individual vessel reports 236 and fleet reports 238 that provide valuable information to the user regarding behavior and performance at various factors related to the events in aggregate.

FIG. 3 shows a detection flow procedure 300 in the example of bridge routines for one or more vessels in a fleet. At the computation phase 310, the sample detectors 312 provided by visual and other detectors include (e.g.) a person crossing or stopping at a location, a person interacting with equipment, a person walking, sitting, not-moving (stationary), a person staring at a location, a person wearing earphones and/or lights off at the location. In the associated data primitives generation phase 320, sample detected metrics 322 are provided, including (e.g.) starting time and ending time, duration, number of participants, the bridge station visited, a protocol step executed and a non-conformity with protocols. Event samples 324 can include participant name(s) identified as performing the shift, when the shift started, whether a given participant's shift was longer or shorter than normal, missing personnel and/or excess/unauthorized personnel on the bridge. In the exemplary information phase sample reports 332 are created that can include (e.g.) shift duration over time, shift participation (head count), equipment interaction time statistics, distribution—for example number of shifts X duration and a location graph (e.g. a heatmap) that can be based upon month, week, day, etc. In the information phase 330, the sample reports 332 can be presented as vessel reports 334 and fleet reports. Sample detected metrics 322 and event samples 324 can be presented to the user as discrete events 338 and complex events 339.

FIG. 4 shows a detection flow procedure 400 in the example of safety rounds for one or more vessels in a fleet. At the computation phase 410, the sample detectors 412 provided by visual and other detectors include (e.g.) the location of the event, person interacting with equipment, person stopping at a location, person walking or staring at a location, person wearing a hard-hat, life vest or other protective equipment and/or holding a safety tool, such as a fire extinguisher, flashlight, etc. In the data primitives phase 420 sample detected metrics can include (e.g.) starting or ending time of an event, duration, number of participants, station visited protocol step executed and/or round-specific protective equipment (PPE) employed. Event samples 424 can include whether a safety round was not performed for a predetermined number of hours and a round taking X % more or less time than normal, a round performed by X number of personnel, a round started late by X minutes, a round performed without needed PPE and/or a round completed in X minutes. The information phase 432 provides sample reports 432, based upon events, including duration over time, participation, safety protocol compliance, station time requirements, distribution (e.g. number of rounds X duration) and/or a graph/heat map based upon month, day, week, etc. Vessel reports 434 and fleet reports 436. The information phase 430 also reports discrete events 438 and complex events 439 based upon sample detected events 422 and event samples 424.

FIG. 5 shows a detection flow procedure 500 in the example of cargo operations for one or more vessels in a fleet. At the computation phase 510, sample detectors 512 can include a pipe connected, a pipe disconnected, a person interacting with equipment, a person standing, arriving or leaving, a person wearing a hard-hat, gloves, goggles and/or other PPE. The data primitives phase 520 provides sample detected metrics 522 include starting and ending time, duration number of personnel participating, a protocol step executed and/or PPE employed in the task(s). Event samples 524 can include a task complete in X minutes, task completion X % larger or shorter than usual, the task performed by X personnel and/or a task performed without (free of) PPE of X type.

V. Collaboration System and Method

A. Overview of Collaboration System Structure and Function

A desirable functionality in communication between one or more ships and shore assets is collaboration regarding the reaction to automatically detected maritime visual events onboard a commercial vessel. Such collaboration provides with an intuitive user experience at a reasonable computational cost and reasonable development cost given the above-described communication challenges between ship and shore and the business relationships and privacy concerned while preserving the context of the detected maritime visual events.

As also described, automatically detected maritime visual events can be a visual event among the categories of crew behavior, crew safety, ship maintenance, ship environment, and active cargo monitoring. The detected events are summarized and displayed on a web-based dashboard both on shore and on the ship.

In an exemplary embodiment, collaboration between ship and shore is bidirectional user-entered data and could include notifications, access to, editing of, and search of comments/virtual whiteboards/screens/sticky notes as well as text chat/video and audio conferencing that are linked to each reported detected visual event. This collaboration capability is intended to allow for reactions to the linked maritime visual events and as well as enriching the detected maritime visual event itself.

Reference is made to FIGS. 17, 18 and 19, which show the above-described system of FIGS. 1, 1A and 2, respectively, including an integrated collaboration application for use with the above-described maritime visual detection system. Many commercially available collaboration tools exist. For example, there are commercially available (proprietary and open source) collaboration applications such as Slack, Hangouts Chat, RocketChat, Glip, Discord, Flowdock, Chanty, Flock, Microsoft Teams, Ryver, Mattermost, Amazon Chime, Faceboot, Twitter. There are also existing, commercially available, visual collaboration platforms such as Miro, Lucidspark, MURAL, iObeya, Creately, Storeboard, Conceptboard, DEON, Bluescape, Ziteboard, Allo, Marimba. A variety of such applications and platforms can be adapted for use with the visual detection and reporting system and method herein using (e.g.) appropriate APIs as described further below. Alternatively a custom, dedicated collaboration system can be provided and integrated with the system and method herein.

To appropriately integrate with the system and method herein, the collaboration functionality (a) is integrated with the maritime detected visual events both from the perspective of data and user experience; (b) handles the relatively low-bandwidth ship-to-shore communications link (say 256 Kb/s) and its often-intermittent nature; (c) manages this link by conserving bandwidth and queuing and prioritizing messages is important for best performance both on ship and shore; and (d) provides the collaboration functionality implementation. Thus, the system of FIGS. 17-19 addresses these needs by integrating the collaboration functionality directly into the maritime visual event database, and ship-based and shore-based dashboards.

As shown in FIG. 17 (with similar functional components being numbered as above), the visual analytics platform 142 includes handling of events and data 1710. Additionally, a collaboration user interface is instantiated on the shore console/workstation 170 and associated dashboard 172. Likewise, each ship in the fleet can include a corresponding collaboration interface 1730 in association with its display 134 and underlying computing device 132. With reference to FIG. 18, the data handled by the system, as described in FIG. 1A above, includes events collaboration data in association with a collaboration interface function 1820 on the shore dashboard 172. Additionally, the communication link 160 transfers collaboration information 1830 along with previously described events and status updates 162. FIG. 19, similarly includes the detection flow 200 now also includes collaboration 1910 within (e.g.) complex events 234.

The process for providing a collaboration feature to the system and method includes the user selecting a context that is either on the shore dashboard 172 or on the ship dashboard 134. That context represents a timestamped maritime visual event. The context can be selected graphically by a user selected a fleet, vessel, time, event type, event location, or some other criteria or the context could be selected from a list. The selected context causes a database lookup in the cloud (e.g. platform 142) for an existing collaboration or local cache of the cloud database for performance reasons. If the context contains an existing collaboration, that collaboration is loaded onto the same user dashboard 134, 172, and the user is given the opportunity to edit and/or respond. If the collaboration is new—that is, not an existing collaboration—then the user is given the opportunity to create a new collaboration. See description of FIG. 23 below.

The new or updated collaboration is stored in (e.g.) cloud data storage, and linked to the automatically detected visual event. Initially, the new or updated collaboration can be stored in the local cache of the computing device for performance reasons.

FIG. 20 shows a generalized procedure 2000 for collaboration by a user on a dashboard. The user initially logs onto the dashboard in step 2010 using credentials, which establish permissions. FIG. 21 shows an exemplary dashboard 2100 that can be presented to the user. This dashboard can include an activity pane 2110 with vessel status, a vessel event pane 2120, which includes visual images 2122 and other indicators 2124 of sensor location and sensor selection 2126. The user navigates to such an event in step 2020 of the procedure 2000. A comment page 2130 with general comments by interested parties is also displayed. This can be a running list of communications generated during collaboration sessions or other comments generated by certain parties. The pane 2120 also include a collaboration tab 2140 that can display the number 2142 of unread comments for a dashboard user. By clicking the tab 2140, the user can initiate collaboration in step 2030, and the dashboard 2100 thereby displays a collaboration pane 2210, as shown in FIG. 22. The pane 2210, more particularly, display notifications generated in the platform for users who are monitoring that visual event—in this example, a new collaboration added for an existing, associated, maritime visual event (e.g., 2122). The user can review existing collaboration comments and associated data, or input new comments and/or data—including—where appropriate and permitted—start a new collaboration with interested parties having relevant access permission.

The collaboration system is created by defining and implementing a set of collaboration API's that should be clear to those of skill in the art. An example collaboration API for comments can employ the well-known functions GET( ), POST( ), PATCH( ), DELETE( ). GET( ) gets the most recent comments for a particular marine visual event. POST( ) posts a new comment or reply into the conversation/collaboration. PATCH( ) updates an existing comment, and DELETE( ) deletes a comment.

As described, the system herein handles the above-described, relatively, low-bandwidth and intermittent connection between ship and shore by queuing and prioritizing updates and notifications using a queuing/prioritization procedure. It can also use a local cache that updates at the local computing device and/or data storage when a connection is available. The system handles any viewing/editing restrictions associated with collaboration data due to system access controls or data privacy. Generally, users who are allowed to view a particular maritime visual event will also be allowed to view and edit the associated collaboration. Also, each collaboration edit or addition is time-stamped and user-stamped.

The system stores and loads the collaboration data so that the collaboration data appears linked to the detected maritime visual events such that the collaboration data enriches the visual events and can appear on reports about the events or in summary form. Again, note that a single visual event detector can run continuously and takes input from a single video camera typically running at 15, 30 or 60 frames per second, and a typical deployment on a ship can involve several or dozens of visual event detectors running on the input from several or dozens of video cameras. Some examples of visual events that can be associated with collaboration are as follows:

1. An example of a crew behavior visual event is that crew members are performing expected activities on the bridge of the vessel such as navigation at the expected time and the event also includes a reported location, start time, end time and elapsed time.

2. An example of crew safety visual event is an alert that the crew members are wearing hard-hats when required to do so by their assigned activity.

3. An example of a ship maintenance visual event is an alert that engine oil is being added to the engine at an appropriate time.

4. An example of a ship environment visual event is an alert that another vessel is in the vicinity.

5. An example of an active cargo monitoring visual event is an alert that the crew members have performed an inspection round on the cargo.

FIG. 23 shows a data flow 2300 for maritime visual events stored in offsite storage (e.g. a storage cloud). This flow consists of a list of indexed items 2310 comprising timestamped events with associated context (i.e. type of event, permissions, etc.). The data can be associated with collaboration where appropriate

B. Collaboration Examples

Examples of collaboration are comments that can be added from either the ship side or shore side dashboards linked to a single visual event at a time. The comments will be visible from either ship side or shore side dashboard whenever that single visual event is accessed. The comments include metadata of when they were added and by whom. In general, the comments' visibility on the dashboard depends on the access permissions of the dashboard user, and such permissions are stored and applied based on the user's login information.

Note, while general contextual commenting (as shown herein) is one form of collaboration contemplated herein, the collaboration application, when linked to a detected maritime event can further include functionality for one or more of (a) simultaneous document editing, (b) whiteboarding, (c) sticky notes, (d) text chat, (e) notification, (f) video conferencing, and/or (g) audio conferencing. Such well known functionalities can be native on the commercially available collaboration application or integrated using appropriate (e.g.) APIs in a manner clear to those of skill.

VI. Conclusion

It should be clear that the above-described system and method effectively provides a user with meaningful information on the status and performance of various activities that are critical to safe and efficient operation of a vessel. This information includes relevant visual information that can be highly beneficial in understanding activities and providing evidence for follow-on analysis, etc. The system and method can operate to deliver meaningful visual and other information in near real time over small bandwidth communication channels. A graphical user interface can be provided to control the system and method, setting priorities, tracking and reporting activities as appropriate. The system and method can also be adapted to operate over larger bandwidth channels and/or with other types of remote locations—for example islands, subterranean/underground, arctic and Antarctic stations, space-based locations, etc. Moreover, the system and method herein allows for active collaboration by interested parties related to specific visual events using various parameters to control/filter access.
